  • Patent number: 11475200
    Abstract: Various implementations described herein are directed to an apparatus having a processor and memory having instructions stored thereon that, when executed by the processor, cause the processor to identify conductive paths in a physical layout of an integrated circuit having nodal features that define a connective structure of the integrated circuit. The instructions may cause the processor to traverse the conductive paths to detect valid metals and redundant metals. The valid metals may refer to valid conductive paths between the nodal features that conjoin the nodal features. The redundant metals may refer to unused conductive paths that provide disjointed paths from the nodal features. The instructions may cause the processor to indicate the valid metals as marked with a first indicator and to indicate the redundant metals as unmarked with a second indicator that is different than the first indicator.

  • Publication number: 20220293522
    Abstract: Various implementations described herein are directed to a method for routing buried power rails underneath a memory instance. The method may identify first rails of the buried power rails disposed in a first layer and second rails of the buried power rails disposed perpendicular to the first rails in a second layer. The method may identify long rails of the first rails with a first length and short rails of the first rails with a second length that is less than the first length. The method may separately couple the long rails and the short rails to the second rails with vias that extend between the first layer and the second layer.
